How to Find or Set Sample Rate in StudioLive 16.0.2

Just moving into ProTools from Logic, steep leaing curve. First project gives an error, "HW device is set at a different sample rate from the open session". How can I find or set the sample rate of my "HW" StudioLive 16.0.2, and which is best practice: 44.1 or 48?

Thanks.
